  legs 
  are 
  much 
  thicker, 
  the 
  middle 
  coxse 
  more 
  widely 
  distant, 
  

   the 
  neck 
  much 
  broader 
  and 
  less 
  abrupt, 
  and 
  the 
  details 
  of 
  

   structure 
  so 
  different 
  that 
  the 
  two 
  have 
  a 
  very 
  different 
  facies. 
  

   Hence 
  the 
  North-American 
  insect 
  should 
  form 
  a 
  distinct 
  

   genus 
  and 
  Phucobius 
  remains 
  peculiar 
  to 
  Japan 
  and 
  China. 
  

  

  Since 
  the 
  above 
  was 
  written, 
  Casey 
  has 
  published 
  a 
  note 
  

   on 
  this 
  genus 
  in 
  Bull. 
  Cal. 
  Ac. 
  Sci. 
  i. 
  p. 
  313, 
  and 
  proposed 
  

   the 
  genus 
  Bryonomus 
  for 
  the 
  North-American 
  species 
  above 
  

   referred 
  to. 
  

  

  Ocypus 
  nigro-ceneus, 
  n. 
  sp. 
  

  

  Elongatus, 
  parallelus, 
  angustulus, 
  niger 
  ; 
  capite 
  thoraceque 
  nigro- 
  

   aeneis, 
  nitidis, 
  haud 
  pubescentibus 
  ; 
  elytris 
  abdomineque 
  opacis 
  ; 
  

   antennis 
  extrorsum 
  rufis. 
  

  

  Long. 
  20 
  milliin. 
  

  

  Antennas 
  short, 
  black 
  at 
  the 
  base, 
  red 
  at 
  the 
  apex, 
  the 
  two 
  

   or 
  three 
  penultimate 
  joints 
  transverse. 
  Head 
  nearly 
  as 
  broad 
  

   as 
  the 
  thorax, 
  very 
  densely 
  punctured 
  except 
  along 
  the 
  

   middle. 
  Thorax 
  about 
  as 
  long 
  as 
  broad, 
  shining 
  brassy 
  

   black, 
  numerously 
  punctured 
  with 
  punctures 
  of 
  moderate 
  size, 
  

   and 
  smaller 
  ones 
  intermixed 
  ; 
  a 
  well-marked 
  space 
  along 
  

   the 
  middle 
  smootli 
  ; 
  scutellum 
  clothed 
  with 
  black 
  pile. 
  Elytra 
  

   dull 
  black, 
  scarcely 
  brassy, 
  sculpture 
  indistinct. 
  Hind 
  body 
  

   not 
  variegate. 
  

  

  This 
  is 
  closely 
  allied 
  to 
  our 
  European 
  0. 
  fuscatus, 
  but 
  is 
  

   larger 
  and 
  has 
  numerous 
  points 
  of 
  distinction.

  Nanai; 
  Hakodate, 
  Sept. 
  1880; 
  eight 
  examples. 
  

   I 
  have 
  the 
  species 
  also 
  from 
  Olga 
  Bay, 
  on 
  the 
  coast 
  of 
  Korea.

  This 
  remarkable 
  insect, 
  though 
  very 
  rare, 
  has 
  been 
  found 
  

   in 
  all 
  the 
  three 
  islands 
  of 
  the 
  group. 
  Shiba 
  at 
  Tokio, 
  Nara 
  

   near 
  Kiota 
  and 
  Nanai, 
  Hakodate, 
  are 
  localities 
  for 
  it.
